WebClient webClient = new WebClient(BrowserVersion.FIREFOX_78);
webClient.getOptions().setJavaScriptEnabled(true);
webClient.getOptions().setThrowExceptionOnScriptError(false);

String url = "https://example.com";
HtmlPage page = webClient.getPage(url);

List<DomNode> paragraphs = page.getByXPath("//p");

for (DomNode paragraph : paragraphs) {
    System.out.println(paragraph.asText());
}

webClient.close();
